SOLUTION

∵segmentis tangent to the circle at point C.

∴∠MCA=∠MCB=90°

Suppose

From the Pythagorean theorem

MA²=9²+²

MB²=4²+²

∴MA²+MB²=AB²

i.e.

We conclude that

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
